Odin notices that word. Might. As though even Loki was not certain if this woman he loved so dearly would grieve his death.
Odin wonders if she did. If she felt for Loki as he did her. He wonders if he should call for her. He wonders if, perhaps, one of the older children might be Loki's, or if even the younger child is. There was enough time during his absence from the throne for such a thing...
He picks the book back up, hoping to find out if he has grandchildren, but hesitates as he turns the page, wondering if they look Aesir or not.
